PokerStars hand history deleted upon Installation of Hand2Note free

I just recently installed Hand2Note's free version and all of my hand history from PokerStars says it was "recently modified" but the folders themselves are now empty. I uninstalled and reinstalled Hand2Note free (which I hope hasn't messed anything up), but where would those hand histories be located now? Did Hand2Note place them somewhere else, or are they gone forever now?
